Why are you trying to compile a MACOSX version on MS Windows ?
I am not sure which files you are referring to as "attached file" ?

You need to compile the c file into a mex library (in matlab).
Setup your Matlab's mex compiler:
>> mex -setup then run the .m file

Correcting an old post.
Walter's comment above is incorrect. When mexing a source file, you need to use the file name including the extension. So if you had ghoatbleet.c then you would issue the following at the command line:
mex ghoatbleet.c
If you issue the command without the .c extension, MATLAB will search for the file name without the extension, not find it, and report a file not found error.
